FNIRSI® NVS-40 4K HD Binocular Night Vision Infrared 6x Digital Zoom

FNIRSI® NVS-40 4K HD Binocular Night Vision Infrared 6x Digital Zoom

Product Description

The FNIRSI NVS-40 is a digital night vision binocular built for observing and recording in both daylight and complete darkness. Designed as a dual-use device, it functions as a standard color-viewing binocular during the day and switches seamlessly into infrared-assisted night vision when light disappears, making it a versatile tool for anyone who needs reliable visibility across changing lighting conditions.

At the core of the NVS-40 is an 850nm infrared illumination system paired with a 3-inch HD color screen, giving users a clear, real-time view of their surroundings rather than the dim green tint associated with older analog night vision devices. In daylight or low-light conditions, the observation range extends from 2 meters out to infinity, while full darkness performance reaches up to 300 meters using its infrared capability. A 6x digital zoom lets users bring distant subjects closer without needing to physically approach them, which is particularly useful for wildlife observation, security monitoring, or scouting terrain from a fixed position.

Beyond simple observation, the NVS-40 doubles as a capable recording device. It supports 4K (3840×2160) video capture along with several lower resolution options, including 2K, 1080P Full HD, 720P, VGA, and QVGA, giving users flexibility depending on storage needs or intended use. For still images, the device can capture photos at resolutions up to 36MP, making it suitable for documenting wildlife sightings, surveillance footage, or outdoor excursions in sharp detail. A built-in microSD card slot, supporting a 32GB card, handles on-device storage, while a USB interface allows for firmware updates and easy file transfer to a computer.

White balance settings add further control over image quality, with automatic detection alongside manual presets for daylight, cloudy, tungsten, and fluorescent lighting, helping the device adapt to whatever environment it's used in. Power comes from a rechargeable 18650 battery, charged through a USB Type-C port at 5V/1A, which avoids the ongoing cost and waste of disposable batteries during extended use in the field. The interface supports multiple languages, including English, French, German, Russian, Spanish, Portuguese, Japanese, and Chinese, making the device accessible to a broad international user base.

Built with a plastic housing for a manageable weight, the NVS-40 is suited for hunters, campers, hikers, and wildlife enthusiasts who need extended visibility after dark, as well as security-conscious users who want a compact device capable of both observation and evidence-grade recording. Its combination of daytime color viewing, long-range infrared night vision, and high-resolution photo and video capture make it a practical all-in-one optical tool rather than a single-purpose night vision unit.
